Abstract

A skirt-and-piston assembly divides an interior space of casing (2) into the chambers (8,10). A distributor-plunger (32) having a sensor applies the force of control rod (28) to hydraulic piston. A sleeve (54) is mounted to slide in leak-tight manner with respect to pneumatic piston (12) along longitudinal axis. A three-way valve has valve shutter pressed against the valve seats. A securing element is provided for connecting the sleeve to pneumatic piston. The securing element has a mechanism for gradually moving the sleeve according to movement of piston.
